Airworthiness Directives; Airbus Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

-----------------------------------------------------------------------

SUMMARY: We propose to supersede Airworthiness Directive (AD) 2004-23-
20 for certain Airbus Model A300 series airplanes and Model A300 B4-
601, A300 B4-603, A300 B4-620, A300 B4-622, A300 B4-605R, A300 B4-622R, 
A300 F4-605R, and C4-605R Variant F airplanes. AD 2004-23-20 currently 
requires, for certain airplanes, repetitive inspections for cracking 
around certain attachment holes, installation of new fasteners for 
certain airplanes, and follow-on corrective actions if necessary. AD 
2004-23-20 also requires modifying certain fuselage frames, which 
terminates certain repetitive inspections. Since we issued AD 2004-23-
20, we received a report indicating that the material used to 
manufacture the upper frame feet was changed and negatively affected 
the fatigue life of the frame feet. This proposed AD would reduce the 
compliance times for the initial inspection and the inspection 
intervals. This proposed AD would also expand the applicability and 
require an additional repair on certain airplanes that have been 
modified. We are proposing this AD to prevent cracking of the center 
section of the fuselage, which could result in a ruptured frame foot 
and reduced structural integrity of the airplane.

DATES: We must receive comments on this proposed AD by March 17, 2016.

Discussion

    On November 10, 2004, we issued AD 2004-23-20, Amendment 39-13875 
(69 FR 68779, November 26, 2004) for all Airbus Model A300 series 
airplanes and Model A300 B4-601, A300 B4-603, A300 B4-620, A300 B4-622, 
A300 B4-605R, A300 B4-622R, A300 F4-605R and A300 C4-605R Variant F 
airplanes. (That AD superseded AD 2001-06-10, Amendment 39-12157 (66 FR 
17490, April 2, 2001)). AD 2004-23-20 requires actions intended to 
address an unsafe condition on the products listed above.
    Since we issued AD 2004-23-20, Amendment 39-13875 (69 FR 68779, 
November 26, 2004) we received a report indicating that a change in 
material for manufacturing the frame feet for certain airplanes 
negatively impacted the fatigue life of the frame feet.
    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA 
Airworthiness Directive 2013-0295, dated December 11, 2013 (referred to 
after this as the Mandatory Continuing Airworthiness Information, or 
``the MCAI''), to correct an unsafe condition for Airbus Model A300 B4-
601, A300 B4-603, A300 B4-620, A300 B4-622, A300 B4-605R, A300 B4-622R, 
A300 F4-605R, and A300 C4-605R Variant F airplanes. The MCAI states:

    During a scheduled inspection of the fuselage frame feet of an 
in-service A300-600 aeroplane, cracks were observed in Frame (FR) 
43, FR 44, FR 45 and FR 46 between stringer (STGR) 24 and STGR 30.
    This condition, if not detected and corrected, could affect the 
structural integrity of the aeroplane.

[[Page 5057]]

    To address this unsafe condition, [Direction Generale de 
l'Aviation Civile] DGAC France issued [an] AD * * * to require 
repetitive inspections of the affected frames and stringers on both 
sides of the fuselage and, depending on findings, repairs, as 
specified in Airbus Service Bulletin (SB) A300-53-6122.
    Subsequently, DGAC France issued AD F-2004-002 [http://ad.easa.europa.eu/ad/F-2004-002] (EASA approval 2003-2108) [which 
corresponds to FAA AD 2004-23-20, Amendment 39-13875 (69 FR 68779, 
November 26, 2004)], retaining the requirements of [an] AD * * * and 
required the embodiment of Airbus SB A300-53-6125 (Airbus 
modification 12168) in order to improve the life of the frame foot 
attachment.
    Since DGAC France AD F-2004-002 was issued, a fleet survey and 
updated Fatigue and Damage Tolerance analyses were performed in 
order to substantiate the second A300-600 Extended Service Goal 
(ESG2) exercise.
    It was highlighted that the frame feet material change from 
2024T3511 (A300B4) to 7175T7351 (A300-600) had an impact on the 
frame feet fatigue life duration. Airbus SB A300-53-6122 was revised 
accordingly to decrease the inspection thresholds and intervals. 
Subsequent SB revision introduced a second structural modification 
point (SMP2) for aeroplanes that embody Airbus SB A300-53-6125 
(modification 12168).
    For the reasons described above, this new [EASA] AD retains the 
requirements of DGAC France AD F-2004-002, which is superseded, but 
requires those actions within the new thresholds and intervals as 
specified in Revision 04 of Airbus SB A300-53-6122.

    The retained requirements include rototest inspections for cracking 
in the area surrounding the frame feet attachment holes between 
fuselage FR 41 and FR 46 from stringers 24 to 28 on the left and right 
sides, and related investigative and corrective action if necessary. 
The related investigative actions include additional rotating probe 
inspections of the adjacent holes. The corrective actions include 
reaming out cracks, cold working fastener holes, and installing 
oversized fasteners, or repair. This proposed AD also expands the 
applicability to include airplanes on which Airbus Modification 12168 
was done. You may examine the MCAI in the AD docket on the Internet at 
http://www.regulations.gov by searching for and locating Docket No. 
FAA-2016-0451.

Related Service Information Under 1 CFR Part 51

    Airbus has issued Service Bulletin A300-53-6122, Revision 04, dated 
February 27, 2012. The service information describes procedures for the 
repetitive inspections of certain frame feet attachment holes for 
cracks, installation of new fasteners, and repair of cracked areas.
    In addition, Airbus has issued Service Bulletin A300-53-6125, 
Revision 01, dated June 13, 2003. The service information provides 
compliance times for certain airplanes to do the proposed modification.
    Airbus has also issued Service Bulletin A300-53-6125, Revision 04, 
dated March 17, 2015. The service information describes procedures for 
the modification of certain upper frame feet fittings.
    This service information is reasonably available because the 
interested parties have access to it through their normal course of 
business or by the means identified in the ADDRESSES section.

FAA's Determination and Requirements of This Proposed AD

    This product has been approved by the aviation authority of another 
country, and is approved for operation in the United States. Pursuant 
to our bilateral agreement with the State of Design Authority, we have 
been notified of the unsafe condition described in the MCAI and service 
information referenced above. We are proposing this AD because we 
evaluated all pertinent information and determined an unsafe condition 
exists and is likely to exist or develop on other products of the same 
type design.

Changes to AD 2004-23-20, Amendment 39-13875 (69 FR 68779, November 26, 
2004)

    This proposed AD would retain all requirements of AD 2004-23-20, 
Amendment 39-13875 (69 FR 68779, November 26, 2004). Since AD 2004-23-
20 was issued the AD format has been revised, and certain paragraphs 
have been rearranged. As a result, the corresponding paragraph 
designators have changed in this proposed AD, as listed in the 
following table:

                      Revised Paragraph Designators
------------------------------------------------------------------------
   Requirement in AD 2004-23-20,
  Amendment 39-13875 (69 FR 68779,    Corresponding requirement in this
         November 26, 2004)                      proposed AD
------------------------------------------------------------------------
             paragraph (f)                       paragraph (g).
             paragraph (g)                       paragraph (h).
             paragraph (h)                       paragraph (i).
             paragraph (i)                       paragraph (j).
             paragraph (j)                       paragraph (k).
------------------------------------------------------------------------

    We have converted ``TABLE 1.--SERVICE INFORMATION'' in AD 2004-23-
20, Amendment 39-13875 (69 FR 68779, November 26, 2004) to text in 
paragraphs (j)(3)(i) and (j)(3)(ii) of this proposed AD for formatting 
purposes only.
    We have also moved the service information acceptable for 
compliance if previously done from ``TABLE 1.--SERVICE INFORMATION'' in 
AD 2004-23-20, Amendment 39-13875 (69 FR 68779, November 26, 2004) to 
paragraph (r)(2) of this proposed AD.

Costs of Compliance

    We estimate that this proposed AD affects 65 airplanes of U.S. 
registry.
    The actions that are required by AD 2004-23-20, Amendment 39-13875 
(69 FR 68779, November 26, 2004), and retained in this proposed AD take 
about 90 work-hours per product, at an average labor rate of $85 per 
work-hour. Required parts cost about $4,000 per product. Based on these 
figures, the estimated cost of the actions that were required by AD 
2004-23-20 is $11,650 per product.
    We also estimate that it would take up to 109 work-hours per 
product to comply with the basic requirements of this proposed AD. The 
average labor rate is $85 per work-hour. Required parts would cost up 
to $6,070 per product. Based on these figures, we estimate the cost of 
this proposed AD on U.S. operators to be $996,775, or $15,335 per 
product.
    We have received no definitive data that would enable us to provide 
cost estimates for the on-condition actions specified in this proposed 
AD.

Authority for This Rulemaking

    Title 49 of the United States Code specifies the FAA's authority to 
issue rules on aviation safety. Subtitle I, section 106, describes the 
authority of the FAA Administrator. ``Subtitle VII: Aviation 
Programs,'' describes in more detail the scope of the Agency's 
authority.
    We are issuing this rulemaking under the authority described in 
``Subtitle VII, Part A, Subpart III, Section 44701: General 
requirements.'' Under that section, Congress charges the FAA with 
promoting safe flight of civil aircraft in air commerce by prescribing 
regulations for practices, methods, and procedures the Administrator 
finds necessary for safety in air commerce. This regulation is within 
the scope of that authority because it addresses an unsafe condition 
that is likely to exist or develop on products identified in this 
rulemaking action.

Regulatory Findings

    We determined that this proposed AD would not have federalism 
implications under Executive Order 13132. This proposed AD would not 
have a substantial direct effect on the States, on the relationship 
between the national

[[Page 5058]]

Government and the States, or on the distribution of power and 
responsibilities among the various levels of government.
    For the reasons discussed above, I certify this proposed 
regulation:
    1. Is not a ``significant regulatory action'' under Executive Order 
12866;
    2. Is not a ``significant rule'' under the DOT Regulatory Policies 
and Procedures (44 FR 11034, February 26, 1979);
    3. Will not affect intrastate aviation in Alaska; and
    4. Will not have a significant economic impact, positive or 
negative, on a substantial number of small entities under the criteria 
of the Regulatory Flexibility Act.

List of Subjects in 14 CFR Part 39

    Air transportation, Aircraft, Aviation safety, Incorporation by 
reference, Safety.

The Proposed Amendment

    Accordingly, under the authority delegated to me by the

(l) New Definition for This AD: Average Flight Time (AFT)

    For the purpose of this AD, use the parameters specified in 
paragraphs (l)(1), (l)(2), and (l)(3) of this AD to determine the 
applicable AFT for the actions required by paragraph (m) and 
compliance times required by paragraph (n) of this AD.
    (1) The initial inspection compliance time, as the total 
accumulated flight hours counted from take-off to touch-down, 
divided by the total accumulated flight cycles as of the effective 
date of this AD.
    (2) The first repetitive inspection interval, as the total 
accumulated flight hours divided by the total accumulated flight 
cycles at the time of the inspection.
    (3) The second inspection interval and subsequent, as the flight
